Reiscued Dec. 2, 1930 UNITED S A-res PATENT OFFICE GIDEDH SUNDBAOK, OFHEADVILLE, PENNSYLVANIA, ASBIGNOB '10 HOOKLESS FAB- TEN'ER COMPANY, ACORPORATION OF PENNSYLVANIA FA STENEB Original application flied April2, 1917, Serial No. 159,189. Divided and application filed August 15,1821, Serial Io. 498,621- l'etent 110. 1,608,188, dated September8,1182. Application for reissue died December 8, 1829. Serial No.411,357.

This invention relates to fasteners of the type wherein closures for theedges of a garment, curtain, bag, tent or the like are to be separatelyconnected by a fastener which em- 5 bodies a sliding crating devicewhich separates the edges when moved in one direction and closes themwhen moved in the opposite direction. Hitherto in the use of suchfasteners, the degree of separation permitted has been limited by thefact that the edges had to remain joined at at least one point. By anovel arrangement of parts, involving the use of a flexible extensionmember, I have made it possible to secure as wide an opening as may bedesired. By reason of this advantage, In invention is particularlyapplicable to sue articles as corsets, spats, curtains, etc., where wideseparation, without actual disconnection is required. This applicationis a division of my previous application for fastener, Serial No.159,139, filed April 2, 1917, Patent No. 1,403,988, January 17, 1922.

With these and other objects in view, I have devised the apparatusembodying my invention, as described in the following specification andillustrated in the accompanying drawing, of which- Fig. 1 is a plan viewof the device as ordinarily applied,

1 represents a bod having edges 2 which are to be closed. e fastenerembodies stringers 3, 3 composed of tapes having corded edges 4, 4 towhich the interlocking members 5 are clamped in staggered relation. A

sliding hollow Y-sha ed cam 6 fits over members 5 and travels a ongedges 2 to engage or disengage the interlocking members 5 on therespective edges 2. Cam 6 has slotted sides through which the tapesextend laterally but which retain members 5 a ainst forces tending toseparate ed es 2. '%he tapes of stringers 3 are stitche res ectively tothe separate portions of body 1 eyond edges 2. One or both of thestringers 3 are provided at the closing end with stop members 7 passingwithin the slider 6, and engaging the latter to prevent furthermovement.

Beyond the end of body 1 stringers 3, 3

are extended to constitute extensions 8, and

these extensions are connected at their outer ends by link members 9joining the respective stringers. The stringers in effect thusconstitute a single body provided with a slit. Extensions 8 arepreferably provided with m interlocking members 5, and are of such a:lengththat when slider 6 is stopped by link members 9, the body 1 can beseparated to such an extent that the extensions 8, owing to theirflexibility, will straighten out end to end. In the fasteners asheretofore used, without extensions, the end members 9 would directlyconnect the lower end of body edges 2, and slider 6 would consequentlynot go the entire len th, thus preventing complete separation o edges 2.By reason of extensions 8 receiving slider 6, as much opening may besecured as desired, depending on the length of extensions 8. As the freeedges of the ex tension 8 straighten out end to end, the max- 5 imumdegree of separation of the lower edges of body 1 will be about twicethe distance of aha top of slider 6 from the lower edges of Iii Fig. 3,the extension principle is applied 90 to a boned edge corset, andpermits the corset to be put on or taken off without requirin completeopening. 10 is the usual lacing, an 11 is the fastener of thisinvention. The body of the corset ends at 12, and 13 are the extensionmembers. When the slider is moved down to the lower ortion of theextensions 13, these can stretc out end to end to such an extent as topermit the corset to be stepped into or out of without completeseparation, 10o

and when the slider is pulled up the corset will be quickly and firmlyfastened.

In Fig. 4 is shown an application of the extension to a spat, in which14 represents the bod of the spat provided with the fastener as s own,the instep strap 15 being split and carrying the stringer extensions.When the slider 16 is moved down to the extreme bottom, strap 15stretches out end to end and makes such a wide opening that the spat caneasily be slipped on and off the foot without disconnecting the strapfrom the body, as 1s the usual custom. In Fig. 5 the strap 15a is notsplit as in Fig. 4, and only one stringer is connected thereto, thestrap also being sewed only to the body 14 on the side to which thestringer is attached. Thus the slider can go down to the lower end ofthe stringers as in I Fig. 4, and the stringers will stretch out end toend so as to provide the wide opening. Inasmuch as the body of the spat14 overlaps the free side of the strap, it makes no difference that thestrap is not attached to the body on both sides.

InFig. 7 the extension principle is applied to a curtain 17 carried by abody or support 18, such as a tent, automobile top, etc., and thestringer extension 19 is sufficiently long to permit curtain 17 to beswung around relatively to the support when separated. The otherstringer extension appears as attached to body 18 for its entire lengthbut it may be partly free if desired. This arrangement is a decidedadvantage in enabling the curtain to be rolled up.

Another important feature ofmy invention is the locking means which isbest illustrated in Figs. 2, 8 and 9. Asheet metal plate 22 is attachedto the reinforcing loo 23 at the rear end of the slider by means oiextensions 29, which are bent to lie within the loop 23 and serve as apivot about which the plate 22 may be moved. The slider can be positively actuated in either direction by means of the plate 22 whichfunctions as an actuator when lifted upwardly away from the slider andas a slider lock when pushed down so as to lie closely a ainst theslider and overlap the closing en Spring wings 24 project from the platein a position offset from the longitudinal center line of the slider andoffset laterally from the extensions 29. Such wings or projections actto block the passage throu h the slider and prevent relative movementbetween the slider and fastener stringers. Each ofthese wings in theembodiment illustrated, obstructs one of the diverging channels of theslider adjacent its rear end, that is, the wide end of the slider wherethe separated stringers project therefrom, when the plate 22 is swungdownwardly into locking position. They will thus engage the stop member7 and revent their movement outwardly from the slider and thus lock thefasteners against opening.

It will also be apparent that when the slider is thus looked asillustrated in Fig. 2, that the locking wings 24 will project toward andinto proximity to the corded edges 4-4 of the stringers, thus providinga more secure locking effect. In Fig. 2 it will be seen that the lockingwings are positioned directly opposite the slider wedging portion 30. Itwill be of said respective edges for connecting the same, means movableprogressively along said edges to control said connecting means, and anextension beyond said body constituting in effect a continuation of saidedges for receiving said movable means when said edges are disconnected,whereby to increase the separation.

2.
